Description
Technical Field
[0001] The present invention belongs to the technical field of air conditioning, and in particular relates to a heat pipe air wall and an air conditioning system provided with the heat pipe air wall. Background Art
[0002] Existing computer room air conditioners are mainly divided into three levels: room level, row level and cabinet level. Room-level air conditioners have a greater impact on the airflow organization in the computer room. The heat dissipation effects of cabinets in different positions are different, the heating is uneven, and local hot spots are easily generated; the airflow organization of the row-level air conditioner computer room is better than that of the room level, but its cooling efficiency is limited and it cannot withstand the heat dissipation requirements of loads with higher power density; the cabinet-level air conditioner has one-to-one cabinet heat dissipation and good airflow organization, but due to the constraints of the cabinet size, its cooling capacity is small and cannot meet the heat dissipation requirements of high-power single cabinets.
[0003] The heat pipe wind wall is located between the room level and the row level. It has a large cooling capacity and large air volume, and can meet the heat dissipation requirements of high-power density cabinets. Because it uses heat pipe technology, it fully utilizes natural cold sources and reduces the energy consumption of the air conditioning system. However, in the current existing technology, there is a lack of air conditioning systems that fully utilize the advantages of heat pipe wind walls. Summary of the invention
[0004] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a heat pipe air wall.
[0005] In order to achieve the purpose of the invention, the following technical solutions can be used: A heat pipe wind wall comprises a frame, wherein a heat pipe module and a fan module are arranged on the frame, wherein the fan module is arranged on the inner side and / or the outer side of the heat pipe module, and can discharge the hot air between the heat pipe wind wall and the cabinet to be cooled through the outer wall of the first microchannel heat exchanger of the heat pipe module, wherein the first microchannel heat exchanger is connected to a first liquid pipe and a first gas pipe, and a refrigerant flows therein, and the first gas pipe is higher than the first liquid pipe and is connected to an outdoor unit.
[0006] The heat pipe wind wall of the present invention is mainly composed of a heat pipe module and a fan module. The heat pipe module realizes the heat exchange function through the first microchannel heat exchanger, the first liquid pipe and the first gas pipe. The first liquid pipe and the first gas pipe are connected to the first microchannel heat exchanger, and a refrigerant that realizes heat exchange through gas-liquid phase change circulates therein. The refrigerant is preferably R410A refrigerant, which is environmentally friendly and safe, and has no risk of leakage and core burning. In order to balance the internal and external air pressures, a corresponding air inlet is provided on the side of the cabinet away from the heat pipe wind wall to allow natural air to enter. The air takes away the heat after passing through the heat dissipation cabinet. The fan module is used to extract the hot air from the direction of the cabinet to be dissipated. When the air passes through the first microchannel heat exchanger, the heat is absorbed by the refrigerant therein, thereby achieving the effect of lowering the temperature. The cooling principle makes full use of the low temperature of natural air to improve the cooling efficiency. The refrigerant is vaporized into gas phase after being heated, and the gas phase refrigerant rises and enters the first air pipe. The outdoor unit releases the heat of the first air pipe to the outside. The refrigerant is converted into liquid phase after releasing heat and flows back into the first liquid pipe, realizing the circulation of the refrigerant and ensuring continuous heat exchange.
[0007] In the above-mentioned heat pipe wind wall, the heat exchange tubes of the first microchannel heat exchanger () are coiled in a spiral or S-shaped shape to form a vertical first heat absorption surface, the fan module is located on the inner side or outer side of the first heat absorption surface, the outdoor unit includes a condenser assembly connected to the first air pipe, and the first microchannel heat exchanger is provided with heat dissipation fins.
[0008] The heat exchange tubes of the microchannel heat exchanger are coiled in a vertical plane to form a heat exchange surface with a gap that allows air to pass horizontally. The specific coiling method is preferably but not limited to a spiral or S shape. The fan module is located on the side of the heat exchange surface, which can guide the hot air in the direction of the cabinet to the outside through the heat exchange surface. The condenser assembly of the outdoor unit is used to quickly release the heat of the gas phase refrigerant in the first air pipe to realize the circulation of the refrigerant, and the heat dissipation fins are used to further improve the heat exchange efficiency. The specific structural shapes of the condenser assembly and the heat exchange fins are prior art and will not be specifically expanded.
[0009] In the above-mentioned heat pipe wind wall, the fan module includes fan components evenly arranged in a vertical plane, and the fan components are located outside the heat absorbing surface and exhaust air outwards.
[0010] The fan assemblies are also distributed in a vertical plane, which is located on the outside of the first heat absorbing surface and can draw the internal air outward. Moreover, the fan assemblies are arranged in an array. By adjusting the operating power of different fan assemblies in the horizontal and / or vertical direction, the temperature control efficiency at different points can be adjusted, which is conducive to solving the problem of uneven heating of the cabinet.
[0011] In the above-mentioned heat pipe wind wall, a filter assembly is provided on one side of the rack close to the cabinet to be cooled, and the filter assembly includes a filter screen arranged on the rack.
[0012] The filter assembly is specifically implemented by a filter screen that allows air to pass but prevents debris from passing through, thereby effectively preventing external debris from entering and affecting the heat exchange efficiency of the first liquid pipe and the service life of the fan assembly.
[0013] In the above-mentioned heat pipe wind wall, a water collecting tray is also provided at the bottom of the rack, the water collecting tray is located below the first liquid pipe, a drain outlet is provided at the bottom of the water collecting tray, and the drain outlet is connected to the outside of the machine room through a drain pipe.
[0014] Since hot air releases heat when passing through the liquid pipe, the water vapor contained therein may liquefy into water droplets after releasing heat. The water collection tray is used to receive the fallen water droplets and discharge the water to the outside through the drain pipe to avoid damage to related components.
[0015] In the above-mentioned heat pipe wind wall, a compression heat exchange module is also provided on the frame, and the compression heat exchange module includes a second microchannel heat exchanger with refrigerant flowing therein, and the second microchannel heat exchanger forms a vertical second heat absorption surface and is connected to a second liquid pipe and a second air pipe, and the outdoor unit includes a compressor assembly connected to the second air pipe.
[0016] The heat pipe wind wall is also provided with a traditional compression heat exchange module, which can be turned on to improve the heat dissipation efficiency when the heat exchange efficiency of the heat pipe module is insufficient. A heat exchange medium flows in the second microchannel heat exchanger of the compression heat exchange module. The medium enters the second air pipe after being heated and vaporized, and rapidly releases heat under the action of the compressor of the outdoor unit, releasing the heat of the gaseous heat exchange medium to achieve continuous heat exchange. The compressor component is a prior art and will not be elaborated in detail.
[0017] In the above-mentioned heat pipe wind wall, a side of the rack near the cabinet to be cooled is provided with a plurality of temperature measuring components evenly arranged in a vertical plane, the temperature measuring components are electrically connected to a control panel, and the control panel is also electrically connected to each fan component respectively.

DETAILED DESCRIPTION
[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0035] Specific implementation examples Figure 1-5 As shown, the heat pipe wind wall 1 includes a frame 11, on which a heat pipe module 2 and a fan module 3 are provided. The fan module 3 is arranged on the outside of the heat pipe module 2, and can discharge the hot air between the heat pipe wind wall 1 and the cabinet 8 to be cooled through the outer wall of the first microchannel heat exchanger 23 of the heat pipe module 2. The first microchannel heat exchanger 23 is connected to a first liquid pipe 21 and a first air pipe 22, and refrigerant flows therein. The first air pipe 22 is higher than the first liquid pipe 21 and is connected to the outdoor unit 4.
[0036] Specifically, the heat pipe wind wall 1 of the present invention is mainly composed of a heat pipe module 2 and a fan module 3. The heat pipe module 2 realizes the heat exchange function through the first microchannel heat exchanger 23, the first liquid pipe 21 and the first air pipe 22. The first liquid pipe 21 and the first air pipe 22 are connected to the first microchannel heat exchanger 23, and a refrigerant that realizes heat exchange through gas-liquid phase change circulates therein. The refrigerant uses R410A refrigerant, which is environmentally friendly and safe, and has no risk of leakage and burning core. In order to balance the internal and external air pressure, a corresponding air inlet is provided on the side of the cabinet 8 away from the heat pipe wind wall 1 to allow natural air to enter. The air takes away the heat after passing through the heat dissipation cabinet 8. The fan module 3 is used to extract the hot air from the direction of the cabinet 8 to be dissipated. When the air passes through the first microchannel heat exchanger 23, the heat is absorbed by the refrigerant therein to achieve the effect of lowering the temperature. The cooling principle makes full use of the low temperature of natural air to improve the cooling efficiency. The refrigerant is vaporized into gas phase after being heated, and the gas phase refrigerant rises and enters the first air pipe 22. The outdoor unit 4 releases the heat of the first air pipe 22 to the outside. The refrigerant is converted into liquid phase after releasing heat and flows back into the first liquid pipe 21, realizing the circulation of the refrigerant and ensuring continuous heat exchange.
[0037] In this embodiment, the heat exchange tubes of the first microchannel heat exchanger 23 are coiled in an S-shape to form a vertical first heat absorption surface, the fan module 3 is located outside the first heat absorption surface, the outdoor unit 4 includes a condenser assembly connected to the first air pipe 22, and heat dissipation fins are provided on the first microchannel heat exchanger 23. A water collecting pan 12 is also provided at the bottom of the frame 11, the water collecting pan 12 is located below the first liquid pipe 21, and a drain port is provided at the bottom of the water collecting pan 12, which is connected to the outside of the machine room 7 through a drain pipe.
[0038] Specifically, the heat exchange tubes of the microchannel heat exchanger are coiled in a vertical plane to form a heat exchange surface with a gap that allows air to pass horizontally. The specific coiling method is S-shaped. The fan module 3 is located on the side of the heat exchange surface, which can guide the hot air from the cabinet 8 to the outside through the heat exchange surface. The condenser assembly of the outdoor unit 4 is used to quickly release the heat of the gas phase refrigerant in the first air pipe 22 to achieve the circulation of the refrigerant, and the heat dissipation fins are used to further improve the heat exchange efficiency. Since the hot air releases heat when passing through the liquid pipe, the water vapor contained therein may liquefy into water droplets after heat release. The water collection tray 12 is used to receive the fallen water droplets and discharge the water through the drain pipe to avoid damage to related components.
[0039] like Figure 1 As shown, the fan module 3 includes fan components 31 evenly arranged in a vertical plane, the fan components 31 are located outside the heat absorbing surface and exhaust outward. A filter component 5 is provided on one side of the rack 11 near the cabinet 8 to be cooled, and the filter component 5 includes a filter screen 51 arranged on the rack 11.
[0040] Specifically, the fan components 31 are also distributed in a vertical plane, which is located outside the first heat absorption surface and can draw the internal air outward. Moreover, the fan components 31 are arranged in an array, and the temperature control efficiency at different points can be adjusted by adjusting the operating power of different fan components 31 in the horizontal or vertical direction, which is conducive to solving the problem of uneven heating of the cabinet 8. The filter component 5 is specifically implemented by a filter screen 51 through which air can pass but debris cannot pass, effectively preventing external debris from entering and affecting the heat exchange efficiency of the first liquid pipe 21 and the service life of the fan component 31.
[0041] As a further optimization of this embodiment, Figure 3 , 4 As shown, the filter screen 51 ( Figure 1 , Figure 7 The frame 11 (not shown) includes a plurality of parallel vertical rods 52 and a filter screen 53. Adjacent vertical rods 52 are parallel to each other and separated by a spacer 54. Both ends of the spacer 54 are rotatably connected to the vertical rods 52. The filter screen 53 is fixed on the vertical rods 52 to form a filtering surface that can be bent in the horizontal direction but not in the vertical direction. U-shaped slide rails 55 are respectively provided at the upper and lower ends of the frame 11. Both ends of the vertical rods 52 are slidably connected in the slide rails 55. The heat pipe module 2 and the fan module 3 are surrounded in the slide rails 55, and both ends of the slide rails 55 are open to facilitate the loading and pulling out of the filter screen 51. The vertical rods 52 at both ends in the length direction are respectively connected with pull ropes, which are located in the slide rails 55 and connected to the pulling and retracting assembly, so that the filter surface can move and switch between the air inlet side of the heat pipe module 2 and the air outlet side of the fan module 3. When on the air inlet side, that is, when it is located on the side of the rack 11 close to the cabinet 8, it is used to filter the air entering the heat pipe wind wall 1. When on the air outlet side, that is, when it is located on the outside of the fan module 3, the high-speed wind flow output by the fan module 3 is output to the back of the filter surface, which can realize the regeneration of the filter mesh. The pulling and retracting assembly includes a motor, and the output shaft of the motor is connected to the winding roller transmission. The winding roller is connected to the frame 11 in parallel with the vertical rod 52. The end of the pull rope is fixed on the side wall of the output shaft and can be wound on the winding roller. The motor and the winding roller are provided with two groups, which are respectively connected to the two groups of pull ropes to ensure that the filter surface moves back and forth between the filtering position and the regeneration position. In addition, the filter screen 51 also includes a protective grille 56 arranged on the rear side of the frame 11. The protective grille 56 is located between the filtering position of the filter and the cabinet 8. The protective grille 56 is made of hard material and can protect the internal structure of the heat pipe wind wall 1.
[0042] like Figure 1As shown, the frame 11 is also provided with a compression heat exchange module 6, which includes a second microchannel heat exchanger 63 through which refrigerant flows, the second microchannel heat exchanger 63 forms a vertical second heat absorption surface, and is connected to a second liquid pipe 61 and a second air pipe 62, and the outdoor unit 4 includes a compressor assembly connected to the second air pipe 62. A plurality of temperature measuring assemblies evenly arranged in a vertical plane are provided on one side of the frame 11 near the cabinet 8 to be cooled, the temperature measuring assemblies and the compression heat exchange module 6 are electrically connected to the control panel, and the control panel is also electrically connected to each fan assembly 31 respectively.
[0043] Specifically, the heat pipe wind wall 1 is also provided with a traditional compression heat exchange module 6, which can be turned on to improve the heat dissipation efficiency when the heat exchange efficiency of the heat pipe module 2 is insufficient. A heat exchange medium circulates in the second microchannel heat exchanger 63 of the compression heat exchange module 6. The medium enters the second air pipe 62 after being heated and vaporized, and rapidly releases heat under the action of the compressor of the outdoor unit 4, releasing the heat of the gaseous heat exchange medium to achieve continuous heat exchange. The temperature measuring component is used to detect the temperature of the machine room 7. Multiple temperature measuring components can detect the temperature at different positions. The control panel can control the power of each fan module 3 according to the specific temperature conditions, thereby achieving the effect of controlling the temperature at different positions of the machine room 7 to be within a suitable range. In addition, the control panel is located on the side of the fan module 3, that is, outside the air circulation path, to ensure the smooth circulation of air.
[0044] like Figure 6 , 7 As shown. The heat pipe wind wall 1 air conditioning system of this embodiment is arranged in the machine room 7, and a number of heat pipe wind walls 1 are arranged in the machine room 7, and the sides of adjacent heat pipe wind walls 1 are connected. The cabinets 8 to be cooled are arranged in the machine room 7, and a closed heat channel 71 is provided between the heat pipe wind wall 1 and the cabinets 8 to be cooled. The cabinets 8 to be cooled and the heat pipe wind wall 1 are arranged in a straight line on both sides of the machine room 7, and the arrangement directions of the two are parallel to each other. An inlet and outlet 72 is provided on the side wall of the machine room 7 at least at one end of the heat channel 71, and the inlet and outlet 72 is closed by a switch door. An air inlet 73 and an air outlet 74 are respectively provided on both sides of the machine room 7, and the cabinets 8 to be cooled are located between the air inlet 73 and the heat channel 71, and the heat pipe wind wall 1 is located between the air outlet 74 and the heat channel 71.
[0045] Specifically, the heat pipe wind wall 1 air conditioning system of the present invention forms a large heat exchange surface through multiple groups of arranged heat pipe wind walls 1, and the adjacent heat pipe wind walls 1 are connected on the side to ensure the realization of a continuous heat exchange surface. A heat channel 71 is provided between the heat pipe wind wall 1 and the cabinet 8, which is used for the hot air at the cabinet 8 to pass through, so as to flow and output in the direction of the heat pipe wind wall 1. The heat channel 71 is closed except for the opening at the cabinet 8 and the heat pipe wind wall 1, so that the internal airflow is in the direction of flowing from the cabinet 8 to the heat pipe wind wall 1, avoiding the problems of disordered airflow organization and uneven heat dissipation of the cabinet 8. The heat dissipation cabinet 8 and the heat pipe wind wall 1 are arranged in a straight line, and the arrangement directions of the two are parallel, which is conducive to the orderly circulation of the internal air and ensures that the temperature of each cabinet 8 is equivalent. The inlet and outlet 72 at both ends of the heat channel 71 are used for the entry and exit of operators, which is convenient for the inspection and maintenance of the cabinet 8 or the heat pipe wind wall 1. Of course, when the number of cabinets 8 is large, they can be arranged in an array, that is, multiple parallel straight lines. The air inlet 73 is used for natural air to enter, and the air outlet 74 is used for the air discharged from the heat pipe wind wall 1. The natural air passes through the air inlet 73, the cabinet 8, the heat channel 71, the heat pipe wind wall 1, and the air outlet 74 in sequence and is discharged outward. In the process, the heat of the cabinet 8 is absorbed to achieve heat dissipation and cooling of the cabinet 8.
[0046] As an optimization of this embodiment, an air inlet guide 75 with a fan-shaped horizontal cross section is provided on the outside of the air inlet 73. The air outlet side of the air inlet guide 75 is connected to the air inlet 73. Each air inlet 73 corresponds to a group of cabinets 8. The air inlet side is tilted outward. The air inlet sides of each air inlet guide 75 are in the same direction to ensure the air intake efficiency and the air intake uniformity of each air inlet 73. Two air outlet guides 76 are correspondingly provided on one side of each group of cabinets 8 near the heat pipe wind wall 1. The horizontal cross section of the air outlet guide 76 is also fan-shaped. Its air inlet side is connected to the cabinet 8. The air outlet side is tilted toward the heat pipe wind wall 1. The tilt directions of the two air outlet sides of a group of air outlet guides 76 are opposite to each other, which is conducive to the hot air after absorbing the heat of the cabinet 8 to enter the hot channel 71 uniformly.
[0047] Specific working principle: During normal operation, the fan assembly 31 is started, and natural air at room temperature is input from the air inlet 73. After passing through the cabinet 8, the heat is taken away and becomes hot air. The hot air passes through the hot channel 71 and the filter screen 51 and enters the heat pipe wind wall 1, and exchanges heat with the first microchannel heat exchanger 23. The hot air is discharged outward after cooling down. The refrigerant in the first microchannel heat exchanger 23 absorbs heat and gasifies. The gaseous refrigerant rises and enters the first air pipe 22. After absorbing heat in the condenser assembly, it is reliquefied into liquid. The liquid refrigerant returns to the first microchannel heat exchanger 23 along the first liquid pipe 21 under the action of gravity. At the same time, each temperature measuring assembly detects the temperature of the corresponding position in real time and sends the temperature data to the control panel. When the overall temperature gradually increases, the power of the fan assembly 31 is increased; when the power reaches the maximum, but the temperature still exceeds the preset value, the compression heat exchange module 6 is started, and the heat exchange medium circulates between the second microchannel heat exchanger 63, the second air pipe 62, the compressor assembly and the second liquid pipe 61 to improve the heat exchange efficiency. When the temperature of a part of the area is high, the fan assembly 31 at the corresponding position is controlled to increase the power to achieve overall temperature uniformity.
